Reactions are pouring in following the devastating 7.8 and 7.5 magnitude earthquakes that struck Turkey and Syria early Monday morning. There are no estimates available yet as to the number of structures either collapsed or damaged across the region, but a minimum of 3,400 lives have been... View full entry
Four years removed from one of the worst natural disasters in Mexico’s history, one small city in the state of Morelos is ready to bridge the chasm between past tragedy and future optimism thanks to the efforts of one New York firm.

An earthquake safety revolution is spreading along the streets and back alleys of Los Angeles, as steel frames and strong walls appear inside the first-story parking garages of thousands of apartment buildings.
The construction is designed to fix one of the most dangerous earthquake risks: Wood apartment buildings collapsing because the skinny poles propping up parking at the ground level are not strong enough to withstand the shaking.

A building permit analysis conducted by The Los Angeles Times has found that over 27% of Los Angeles’s 11,400 "soft story" wood-frame apartments have been retrofitted since 2015 when the city passed an aggressive seismic upgrading ordinance. "Soft story" buildings are built with an... View full entry
On Thursday, the California Governor’s Office of Emergency Services will unveil an app created by UC Berkeley that will give all Californians who download it on iOS and Android phones the chance to get earthquake early warnings from any corner of the state.
Authorities will also begin issuing quake early warnings through the Wireless Emergency Alerts system, offering text message alerts even for people who have not downloaded the app.
— The Los Angeles Times
The new warning system will alert Californians who have the app when an earthquake registering at level 3 on the Modified Mercalli Intensity Scale strikes nearby. The state will send out text message alerts over its Wireless Emergency Alerts system to anyone within range of a level... View full entry
Although no campus buildings were deemed to be in the worst category, “dangerous,” six at UC Berkeley and three at UCLA were found to have a “severe” risk to life. The remaining 62 at UC Berkeley and 15 at UCLA were said to have a “serious” risk to life, according to the first reports released this week in response to a UC Board of Regents 2017 directive calling on every campus to undertake a seismic risk assessment. — The Los Angeles Times
The list includes some of both campus's most historic and important buildings, including Berkeley's architecture building, Wurster Hall, and UCLA's Powell Library. A potential 2020 ballot measure and a recently-proposed California State Senate bill could provide funding to make necessary retrofits. View full entry
Japan, through both government mandates and its engineering culture, builds stronger structures capable of withstanding earthquakes and being used immediately afterward. The United States sets a minimum and less protective standard with the understanding that many buildings will be badly damaged.
The two approaches reflect different attitudes toward risk, the role of government and collective social responsibility.

The NYT takes a look at the drastically differing approaches (and ideologies behind them) towards earthquake safety in Japan compared with the United States and asks experts what would be at stake in the greater, urban picture in the anticipated event of a very big earthquake. "The debate over... View full entry
With earthquakes in the news following a pair of recent tremors in California, it’s important to remember that seismic design is an integral and increasingly complex aspect of building design architects work hard to address. An ever-improving standard, seismic codes not only save lives, but also... View full entry
Building codes and standards in many countries require engineers to consider the effects of soil liquefaction in the design of new buildings and infrastructure such as bridges, embankment dams and retaining structures — The Guardian
After the devastating earthquake that hit Indonesia, scientists are relating building collapses to soil liquefaction. When overly saturated soil is heavily loosened by intense seismic activity, particles in the soil lose its bond and contact with each other. Thus resulting in its loss of stiffness... View full entry
Yesterday, a magnitude 6.4 quake struck the Taiwanese city of a Hualien, Taiwan. So far, in its wake, the damage has left seven dead and injured 262 others; sixty-three people still remain unaccounted for. according to CNN. Since, emergency workers have been working diligently to rescue those who... View full entry
Los Angeles city officials and property owners are making progress on retrofitting the types of apartment buildings that proved especially vulnerable in the 1994 Northridge earthquake. [...]
As of this month, retrofits on 608 “soft-story” buildings are complete and another almost 4,000 retrofits are in progress, according to the mayor’s office. More than 13,000 of an estimated 13,500 soft-story buildings have been issued orders to comply, the first step on the road to retrofitting.

Commemorating the 24-year anniversary of the 1994 Northridge Earthquake which devastated the greater Los Angeles area on January 17, Curbed LA reports about the status of LA Mayor Eric Garcetti's effort to retrofit all of the city's 13,500 "soft-story" buildings — like the ubiquitous, and...

Yesterday, Mexico City was struck by a powerful 7.1-magnitude earthquake. As of today, over 200 people have been reported dead as rescuers continue their efforts to recover those still trapped in the rubble. Dozens of buildings in and around the city were reduced to rubble and many more, severely... View full entry
The historic Japanese city of Kumamoto, famous for its picturesque 15th century castle, experienced a damaging earthquake in 2016, leading to the demolition of several of its historic buildings.

The head of an influential charity in Italy has said that it is not feasible to rebuild all of the Medieval villages reduced to rubble by yesterday’s earthquake, as it would be too costly and the region has been depopulating anyway.
Instead, the strategic plan for the mountainous area northeast of Rome should be “rethought completely”, said Paolo Beccegato, vice director of the Catholic charity Caritas, which has workers assisting in the devastated zone.

Most of the Bay Area roads, bridges, water systems, dams and levees fared well in Sunday's 6.0 earthquake near Napa, but the damage in the picturesque Wine Country town was a jolting reminder of the vulnerability of public services for 7 million people. A Big One -- such as a 7.0 earthquake on the Hayward Fault that runs beneath heavily populated Oakland and Berkeley -- would inflict more damage to key infrastructure, experts said. — San Jose Mercury News
Overall, the damage caused by the Napa earthquake could have been a lot worse. But a Los Angeles Times article documenting how even retrofitted historic buildings were damaged showcases the profound vulnerability of older structures in California. According to the article: "The destruction... View full entry
"Low-rise buildings collapsed on at least two islands and historic churches cracked and crumbled during the quake," , "which sparked panic, cut power and transport links and forced hospitals to evacuate patients."
The quake also damaged tourist attractions, such as the famed Chocolate Hills of Bohol. A photo of the damage to one hill that was by tourist Robert Michael Poole.
